摘要

本研究旨在探讨决定自由潜水员最大静态呼吸暂停潜水时间的因素。我们将一些物理/生理因素与男性自由潜水员的最长呼吸暂停潜水时间进行了关联。36 名经验丰富的男性自由潜水员参加了此次研究。潜水员参加了两天的实验。第一天,在泳池进行呼吸暂停潜水前、中、后测量了呼吸暂停潜水时间、血氧饱和度(SpO2)、心率(HR)、血压(BP)、压力指数和血液参数。第二天,在实验室测量身体成分、肺活量、静息和最大耗氧量(VO2max)以及 Wingate 无氧功率。使用 SPSS 22 程序对数据进行了皮尔逊相关分析。判定相关系数(R)定为 0.4,显著性水平定为 P 2,肺活量与最大呼吸暂停时间的相关系数 R>0.4,P2、压力指数、总胆固醇与最大呼吸暂停潜水时间的相关系数(R>-0.4,P0.05)。结论是,更多的自由潜水经验、减少体脂、扩大 SpO2 范围和增加肺活量是预测自由潜水性能的指标,有利于自由潜水员提高最大呼吸暂停潜水性能。

Physical and Physiological Predictors Determining the Maximal Static Apnea Diving Time of Male Freedivers.

This study aimed to investigate what factors determine freedivers' maximal static apnea dive time. We correlated some physical/physiological factors with male freedivers' maximum apnea diving duration. Thirty-six experienced male freedivers participated in this study. The divers participated in two days of the experiments. On the first day, apnea diving time, blood oxygen saturation (SpO2), heart rate (HR), blood pressure (BP), stress index, and blood parameters were measured before, during, and after the apnea diving in the pool. On the second day, body composition, lung capacity, resting and maximal oxygen consumption (VO2max), and the Wingate anaerobic power were measured in the laboratory. The data were analyzed with Pearson's Correlation using the SPSS 22 program. The correlation coefficient (R) of determination was set at 0.4, and the level of significance was set at p <0.05. There were positive correlations of diving experience, maximum SpO2, and lung capacity with the maximum apnea time R>0.4, P<0.05). There were negative correlations of BMI, body fat percentage, body fat mass, minimum SpO2, stress index, and total cholesterol with the maximum apnea diving time (R>-0.4, P<0.05). No correlations of age, height, weight, fat-free mass, skeletal muscle mass, HR, BP, blood glucose, beta- hydroxybutyrate, lactate, and hemoglobin levels with the maximum apnea diving time were observed (R<0.4, P>0.05). It is concluded that more experience in freediving, reduced body fat, extended SpO2 range, and increased lung capacity are the performance predictors and beneficial for freedivers to improve their maximum apnea diving performance.
